The B4UFLY app provides model aircraft users with situational awareness and considers the user’s current or planned location in relation to operational restrictions to derive a specific status indicator. The color and shape coded status indicators inform the user if model aircraft operation is prohibited, requires the user to take certain actions, or if there are no FAA operating restrictions other than flying safely. All model aircraft operations must always yield the right-of-way to manned aircraft.

Key features include:
- Heads-Up Status View for quick “at-a-glance” review of current status
- Map Interface to plot nearby flight restrictions
- Planner Mode - an advanced user feature to “plan” for different flight locations and times
- More Info - helpful links for using the B4UFLY app and additional FAA resources

Better but still bug-ridden, crashes under IOS 11


Crashes under IOS 11. Come on FAA you’ve only known IOS release coming for 6 months.
Maps still take forever to load. Do the developers realize that most often used when out at flight location where there is no WIFI?
Initial warning screen doesn’t do anything to help avoid flying near emergency services. UAV pilots want to avoid endangering fire fighters but unless app can provide some indication that something is happening near the flight’s location what good is it? If I can get a pop up alarm when I walk into a store that something is on sale, why can’t FAA work with Google to get pop up on Google maps?
Still shows 5 nm radius for any hospital that has an emergency room with a helipad. Don’t helicopters take off and land vertically? Hospital phone numbers for notifications are often wrong or go to facilities department answering machine. This is bureaucracy over activities that enhance safety.

If FAA can’t get funding to develop and maintain a usable app then team with the commercial app builders such as AIRMAP or Kittyhawk.

Slow, doesn’t update properly.


I tried using this and it is incredible that ANYBODY would EVER suggest it.
Open it up, right away tells me what I already know. I’m within 5 mi of an airport, click list of already I’m smarter than this app.
Exactly what I expected from a govt app. Nearly useless except to tell you that your breaking the law.
Open up planning. Click to put an address in, hit return and select a date. Try to continue and....nothing.....or even better, a blank map that doesn’t let you do anything....since the app must be doing something let’s say it’s relaying your position to the faa so they can find you and probably have now infected your phone making in impossible to remove

Could definitely be better.


Unfortunately like many others who have downloaded the app, I can’t get it to do anything more than tell me that I am within 5 miles of an airport. Something I am aware of and know all the regulations as well as I took the part 107 exam and passed. Why not start by asking are you in your intended flying location? Are you planing a flight? Are you looking at current weather and restrictions in a certain area? Why not contact some of us and have us work with the app developers so we can achieve both goals, abide by the laws set forth by the FAA and help with our flight planning so we can both benefit.
